SonicWall Email Security Server processes your incoming email in the following sequence or order of judgement:
Connection management (this is connection based list, for example having IP in the allowed IP list would only allow connections from those IP they will still go through normal spam filtering process):
Allowed IP list
Blocked IP list
Reputation IP list
Deferred IP list
Non grey IP list
Greylisted IP list
Capture ATP (additional licensed service)
Corporate Allow list
Corporate Block list
Personal Allow list
Personal block list
Note 1: The more specific address book entries in the corporate address book will only override the per user address book when the entries are dealing with email address to email address or domain to domain entries. Otherwise the more specific address book entry will always override the more general address book entry regardless of its corporate / peruser address book location.
Note 2: Some features (SPF and DKIM) have the option to ignore allowed list. When you say ‘ignore allow lists’ address book will not give a free pass, for that specific feature only. Unchecking the box for Ignore allow lists will give the sender a free pass for that option only.
